buildsys: Fix broken link.asneeded function
Both $(CC_FLAG_ASNEEDED) and $(CC_FLAG_NO_ASNEEDED) never become "y",
must check for non-empty strings.
To keep make 3.80 compatibility "$(if" used only.
Fixes: 7da4d1e7 "buildsys: do not use $(and)".

ldso: Force disable -mlong-calls when compiling ldso for ARC
Even though by default for ARC uClibc gets compiled with
disabled long-calls user may provide UCLIBC_EXTRA_CFLAGS
with "-mlong-calls". With this option uClibc will be
successfully compiled but later it will fail in runtime
because dynamic loader cannot deal with relocations
at least very early on its start.
In particular it will be seen as call to non-relocated
symbol _dl_parse_dynamic_info() which ends-up as a segfault
like this:

Solution to this issue is simple we make sure dynamic
loader never gets compiled with "-mlong-calls" by forcing
"-mno-long-calls" on it.

ldso/ARC: fix DT_RELACOUNT handling
With new binutils supporting DT_RELACOUNT, ldso was crashing as it was
parsing relocs incorrectly.
Apparently that code ran for first time and was never tested.

sigaction: fix for THREADS_NATIVE
Commit 9c4fce55a (nptl: remove sigaction, sigprocmask, and sigfillset from
libpthread) removed pt-sigaction.c from the build to fix static build.
However, since the libc sigaction is weak when HAS_THREADS is enabled, static
build is not be affected. Tested for xtensa, x86, MIPS32 targets.
Fixes nptl/tst-signal7.
Moreover, commit 9193a76bb from the 0.9.33 branch has the right version.
